I used the video link as guide to replace both my chain and sprocket. I cheated and used a grinder with a cutting wheel to cut the chain off.
  1. Remove shifter pedal (10mm)
  2. Remove countershaft sprocket cover (8mm). Clean all that crud out!
  3. flatten washer sprocket nut (hammer and flat head screwdriver)
  4. stand on brake pedal and torque the sprocket nut loose (long breaker/cheater bar + 27mm socket) You can put it in gear if you have but I don't think that's safe.
  5. Loosen the rear the rear sprocket nuts Stand on the rear brake if you have to (14mm)
  6. Use a grinder and cut the chain through. No need to try and grind the rivets off.
  7. Loosen chain adjuster nuts (12mm and 10mm)
  8. Remove cotter pin from axle castle nut (needle nose pliers)
  9. Remove axle (17mm + 24mm)
  10. Slide wheel out.
  11. Remove rear sprocket and install new sprocket. You can torque them now with wheel the off or when wheel is back on.
  12. Remove front sprocket and clean up all the crud in the area.
  13. Install new sprocket with flat side facing you. Don't forget to install the washer before the nut.
  14. Install rear wheel. I use my foot under the wheel to guide it back up. Torque rear sprocket nuts if you have not already.
  15. Stock chain is 106 links. If you have a longer chain, cut it to size. you should count 52 side plates on one side of the chain and cut off the next plate since this is where your master link will be. You can use a chain breaker or your grinder.
  16. Pull your chain through from over the rear sprocket round the front and back.
  17. Lube your master link generously and install the o-rings on it. Squeeze the master link together and install your clip or rivet it. (Pliers, channel locks, riveter)
  18. Adjust chain tension and rear tire alignment.
  19. Torque axle down and reinstall cotter pin.
  20. Torque the front sprocket nut and bend the washer down so the nut will not back off.
  21. Reinstall sprocket cover and shifter.
  22. Press on rear brake.
  23. Lube the chain.
  24. Go for test ride. Take it easy and give the chain some time to break-in and stretch. Don't be popping wheelies or doing burn outs!

Does this make it 52 plates + the master link or 51 plates plus the master link?

It is my opinion that the counter-sprocket nut (as well as clutch basket nut for that mater) should be removed with an impact wrench, and not a breaker-bar. Although it's not ideal to have those little impacts reverberate into your transmission, neither is the linear force placed on your output (input if doing clutch work) shaft/bearings from a breaker-bar.

The method mentioned by others is the most commonly used, BUT this is where I'm breaking from convention. Other than the two nuts I mentioned, I would say an impact wrench has no business being around a motorcycle.

I didn't have my impact with me so I used what I had available but the Impact makes a world of wonder.

No need to remove front sprocket guard if you dont want to, cut your old chain with a grinder or bolt cutters, use your new chains master link to join new chain with old chain, gently pull old chain towards rear of bike and you will pull your new chain onto the sprocket. saves some time if you dont want to bother with all the muck up front.

That's so simple it's genius!

Hey, sorry to revive a thread, but I was using the instructions here, and used a D.I.D. x ring chain with 51 plates plus the master link, and it's way too short. As a matter of fact, I think it would've been really tight anyways. My sprocket sizes are 14 in the front, and 45 in the rear. Can you tell me what I'm doing wrong? Any help would be appreciated!

oh craps. It should be 52 + master since it's a total of 106 links. Not sure why I typed 51 plus master since that's only 104 links. You'll need to get another master to make it work if you have already cut it down to 51 links and add another link.

There's no play at all in the chain if I were to force the master link to connect the chain ends.

Does anyone have any advice? The rear wheel is pushed all the way forward, I'm using JT front and rear sprockets at 14/45, and the chain is brand new.

I ordered a new chain just in case... with 108 links just to be sure.

I feel really Josh.

Is the chain taught when you pull on it? 520 pitch chain and sprockets right? You can attach the old chain with the new to string it through and give you something extra to pull on.

No worries, all is good. It's just absolutely confusing, because I can't understand how a 106 link chain won't fit on my bike.

I have all 520 size parts for the drive; JT sprockets front and rear, and a DID X-ring chain with 106 links. I think I could force it to fit, but there would be no slack.

My long term concern is that if I use the 108 link chain, when the chain stretches down the road will I run out of swingarm to properly give the chain tension?

The pictures will have to wait until I get home, but as far as the adjustment, it's placed all the way forward. I made sure that the rear brake and rotor/sprocket on each side is aligned and seated properly. I will double check upon return.

Fixed it! turns out there was some greasy gunk hidden just on the inside of the swing arm. It was an extremely small couple of bits, but just clearing that allowed the wheel to move forward a couple millimeters and the chain works fine.

Thanks for your help!
